Grants ultra soft bamboo toothbrush with charcoal infused bristles is an eco-friendly way to brush your teeth. The charcoal built into Grants new charcoal toothbrushes helps to fight plaque and bacteria while reducing stains and bad breath. Our handles are made from 100% biodegradable and environmentally sustainable bamboo. The bare bamboo handle can be composted and will safely return to the soil. The bristles aren't compostable but can be recycled (check with your local recycling facility). Each toothbrush is individually sealed in a corn starch wrapper than can be composted and the boxes can be recycled.
